fats play a vital role in maintaining healthy skin and hair, insulating body organs against shock, maintaining body temperature, and promoting healthy cell function. they are also known as lipids. they also serve as energy stores for the body. fats are broken down in body to release glycerol and free fatty acids. the glycerol can be converted to glucose by the liver and thus used as a source of energy. the fatty acids are a good source of energy for many tissues, especially heart and skeletal muscle.
fats form a category of lipid, distinguished from other lipids be their chemical structure and physical properties. Fats are solid at room temperature as opposed to oils which are liquids. this category of molecules is important for many forms of life, serving both structural and metabolic functions. they are an important part of the diet of most heterotrophs (including humans).
there are many different kinds of fat, saturated and unsaturated fats differ in their energy content and melting point, but each kind is a variation on the same chemical structure. all fats consist of fatty acids bonded to a backbone structure, often glycerol.
vitamins A,D,E and K are fat-soluble, meaning they can be digested, absorbed, and transported in conjunction with fats. fats are sources of essential fatty acids, an important dietary requirement.
